Reframe semantic-layer-internals.mdx around the contract the semantic
layer offers an agent: declare what you want (a Semantic Query), KTX
figures out how to compute it. Replaces the old "Context-Aware SQL"
framing with a clear imperative-vs-declarative narrative.
Adds a React Flow component (semantic-layer-flow.tsx) that contrasts a
buggy 4-table agent-authored SQL (chasm trap, LEFT-JOIN-in-WHERE,
hardcoded DATE_TRUNC) against the chasm-safe per-fact CTE SQL the
planner actually emits, including the outer GROUP BY over the requested
dimensions. Both lanes converge into a shared warehouse node and each
SQL card now has parallel bullet notes (failures on the left, KTX
behavior on the right).
Side fixes bundled in:
- include the /ktx basePath in the favicon metadata so the icon resolves
under the production prefix
- migrate docs-site/middleware.ts to docs-site/proxy.ts (Next 16 rename)
- redirect / to /ktx/docs/getting-started/introduction so the apex docs
URL works
- add tests covering the apex redirect, the favicon basePath, and the
middleware-to-proxy rename
- propagate the Semantic Query terminology across the ktx-sl CLI
reference, the context-layer concept page, and the agent-clients /
primary-sources integration pages
- Add Next.js basePath '/ktx' so the docs site mounts under /ktx,
enabling it to be reverse-proxied by docs.kaelio.com.
- Add host-based redirects so docs.ktx.sh and ktx.sh permanently
redirect to https://docs.kaelio.com/ktx, making docs.kaelio.com
the single canonical home for KTX docs.
- Update markdown-preference middleware to be basePath-aware so the
llms.mdx rewrite still fires on /ktx/docs/* requests.
Redirect bare /docs to the introduction page with proper metadata
resolution. Add a test for the redirect. Trim the media type in the
Accept header parser so whitespace around semicolons does not break
markdown content negotiation. Add a test script to package.json.
